The PetroChek portable or online crude and refined hydrocarbon monitor can be used to detect hydrocarbons in freshwater and marine environments. It can be used for a wide range of applications. It is sensitive to low hydrocarbon concentrations, and is ideally suited to real-time monitoring, either as a portable unit, in situ or online. It can provide early warning by first detecting a problem with hydrocarbons, then helping to control the environmental impact and remediation and treatment processes.
Radiological contamination of water is due to the presence of radionuclides, which are defined as atoms with unstable nuclei. In an effort to become more stable, a radionuclide emits energy in the form of rays or high-speed particles. This is called ionizing radiation because it displaces electrons, which creates ions. The three major types of ionizing radiation are alpha particles, beta particles and gamma rays.
Risks, testing & treatment of radionuclides in drinking water
This year's fellowships support the study of harmful algal blooms
The U.S. Environmental Protection Agency (EPA) announced that 105 graduate students across the nation will receive $8.6 million in Science to Achieve Results (STAR) fellowship grants to conduct research on topics ranging from climate change and public health to water quality and sustainability that will have cross-cutting impacts in the environmental science field. The 105 STAR fellows will receive a maximum funding of $42,000 for one year for master’s students and up to two years for doctoral students.
The ChlordioX Plus uses disposable ampermetric sensors to provide portable and user-friendly determination of chlorite in water samples. This method is more economical, less complex and faster than ampermetric titration methods. With a simple and sequential test protocol, no special training is required. Reliable and accurate testing can be completed in just 10 minutes.
Commercial environmental laboratories analyze large numbers of samples per day using approved methods, and produce data that need to be technically sound and legally defensible. The Shimadzu GCMS-QP2010 Series can help meet this need. Whether for analyzing VOCs, semi-volatiles, pesticides, PAHs or PCBs, these powerful instruments offer rapid analysis times, long-term calibration stability and greater uptime/usability with easier system maintenance.
Wagtech water quality testing kits allow all levels of users to test for organisms, analyze key physical characteristics such as turbidity and conductivity, and measure specific chemical parameters such as pH, chlorine and ammonia, using simple, accurate procedures. Testing protocols conform to World Health Organization guidelines for assessment of potable water, and kits are chosen based on testing needs. All equipment is packed in IP67-rated carry cases with energy-efficient battery-operated instruments for use anywhere.
When it comes to drinking water safety, many new innovations are focused on emerging contaminants. One new testing method, however, focuses on something that has plagued drinking water for ages — contamination by fecal matter. Water Quality Products Managing Editor Kate Cline recently spoke with Vladislav V. Yakovlev, developer of the technology, about the new testing method and its potential benefits.
Kate Cline: Briefly describe the new detection method procedure.
A new method for detecting fecal matter in water
With drinking water becoming scarcer due to drought in highly populated areas and drinking water sources becoming more polluted, both individual homeowners and businesses are becoming aware of the need for drinking water conservation. This brings to mind the old saying, “reduce, reuse, recycle.”
Integrating water conservation strategies into water management
S465 Series probes were designed as an alternative to Acu-Trol pH and ORP probes for swimming pool control, industrial, municipal and potable water applications. Constructed of polyphenylene sulfide, the probes offer improved chemical resistance. The sensor technology delivers accurate measurement over a range of 0 to 14 pH or -1,000 to 1,000 mV for ORP.
Legionella occurs naturally in the environment and is most commonly found in water. These bacteria thrive in warmer environments, so they are often found in hot tubs, hot water tanks, cooling towers, larger plumbing systems and decorative fountains.
Proper testing & maintenance help prevent deadly Legionella outbreaks
